THE MEETING The IAU Symposium 160 ASTEROIDS COMETS METEORS 1999 has been held at Villa Carlotta in Belgirate, on the shore of Lago Maggiore (Italy), from June 14 to June 18, 1993. It has been organized by the Astronomical Observatory of Torino and by the Lunar and Planetary Institute of Houston. It has been a very large meeting, with 323 registered participants from 38 countries. The scientific program included 29 invited reviews, 106 oral communications, and 215 posters. The subjects covered included all the aspects of the studies of the minor bodies of the solar system, including asteroids, comets, meteors, meteorites, interplanetary dust, with special focus on the interrelationships between these. The meeting was structured as follows. 5 morning plenary sessions have been devoted to invited reviews on: (1) search programs (2) populations of small bodies (3) dynamics (4) physical observations and modelling (5) origin and evolution. Two afternoon plenary sessions have been devoted to space missions to small bodies and to interrelationships between the different populations. The afternoon parallel sessions have been devoted to: dynamics of comets; Toutatis, Ida, Gaspra; physical processes in cometary comae and tails; meteorites; the cosmogonic message from cometary nuclei; physics of asteroids; the interplanetary dust complex; comet nuclei; meteors; composition and material properties of comets; dynamics of asteroids.
Chronicles the formation of the solar system, particularly how asteroids, comets, and meteors were formed, and relates how astronomers learn about the existence and characteristics of these bodies.
"What are asteroids, comets, and meteors made of? What can scientists do if an asteroid is headed toward Earth? Learn how astronomers prepare for space objects hitting Earth, from tracking them to building asteroid-hunting telescopes. Budding astronomers will learn all about meteors, asteroids, and comets, including the history of asteroids hitting Earth and the differences between space rocks"--
Climb Aboard! Explore the difference between meteor, meteorite, and meteoroid! Investigate comet composition and development and their observation through history! Learn about asteroids! Learn about key astronomers tools such as telescopes and the Deep Impact spacecraft! See an infographic showing a comet's orbit! Did You Know? facts and a Guidebook of Near Earth Objects complete your journey. Aligned to Common Core standards and correlated to state standards.

When many young readers think of space, they just think of the planets, and perhaps the sun and moon. But there's much more to space than just those things. Asteroids, meteors, and comets are just a few of the other things that exist in what we know as space. Readers of this delightful book will learn all about these amazing, often rocky or icy, objects. Fact boxes emphasizing key numbers are included throughout the book, while colorful photographs and diagrams also help visual learners understand many of these figures.
